£150++), but damage can often be repaired permanently and easily if caught early.

However, if you leave a crack to develop, it will progress until it meets the joystick or

gimbal axis and you may be replacing the entire joystick assembly at significant cost.

Always inspect a crack and if you can replace or repair the parts.

Joysticks sometimes crack at the base, either through fatigue or from mechanical

damage (i.e. being dropped). When a crack occurs this almost always introduces

significant play into the control and for safety reasons the joystick must be repaired or

replaced before the set is used again (see Figure 35). As an older set, the 9Z appears to

be particularly susceptible to this sort of damage through fatigue. As fatigue damage

occurs spontaneously, you should periodically inspect your joysticks for cracks.

For this type of crack, you can cheaply replace the stick and base with a new part (see

the procedure in Section 3.4.2). However, one simple way of preventing or repairing

stick cracks is to add a collet to the joystick (see Figure 36). If you fly aggressive
